####14. In the following reactions, $ZnO$ is respectively acting as a/an
(2017 Main)
(i) $ZnO+Na _2 O \longrightarrow Na _2 ZnO _2$
(ii) $ZnO+CO _2 \longrightarrow ZnCO _3$
(a) base and acid
(b) base and base
(c) acid and acid
(d) acid and base
Show Answer
Solution:
- Zinc oxide $(ZnO)$ when react with $Na _2 O$ it act as acid while with $CO _2$ it act as base. Therefore, it is an amphoteric oxide.
